Controlling the SD-90 via MIDI
Editing the MFX effect parameters
You can edit effect parameters such as equalizer gain and frequency, delay time, and feedback level.
*
The MFX effect parameters will sometimes be included in the sound parameters (PART), and sometimes be outside
the sound (COMMON). The address will differ depending on which of these is being referenced, as specified by
“MFX source.”
When MFX source = PART
When MFX source = PART (i.e., when editing the MFX of an enhanced sound), transmit the following
system exclusive data.

Address (p1 p2):
when editing the insertion effect for part 1 =11 00
when the sound is a drum set =11 10
when editing the insertion effect for part 2 =11 20
when the sound is a drum set =11 30
when editing the insertion effect for part 3 =11 40
when the sound is a drum set =11 50
Addressr1 r2:
when editing parameter number 1 =06 11
when editing parameter number 2 =06 15
: (the address will increment 04H each time the parameter number increases by 1)
when editing parameter number 29 =07 01
when editing parameter number 30 =07 05
when editing parameter number 31 =07 09
when editing parameter number 32 =07 0D

Effect parameter
The lower 4 bits of the four data bytes indicate a signed numerical value.
Checksum (ss):
For details on the calculation method, refer to “Calculating the checksum” in “MIDI
implementation” (MIDIImple_E.pdf) on the included CD-ROM.

Data byte expression
The value to be specified is first expressed as a
16-bit hexadecimal
in which
32768 = 8000H
is 0.
Each digit is input in the lower place of each data byte.
